AMD Ryzen 5 3580U

The AMD Ryzen 5 3580U is a mobile processor from the 3000 series, built on the Zen+ architecture under the Picasso codename. It integrates four cores with eight threads, base clocked at 2.10 GHz and boosting to 3.70 GHz, within a 15 W TDP class. The chip includes Radeon Vega 9 integrated graphics and supports DDR4 memory over a dual-channel bus, with a shared 4 MB L3 cache. Benchmark data places it at the 43rd percentile among all CPUs, with an average benchmark score of 1745.

How It Compares

Against the Intel Core i5-8269U, the Ryzen 5 3580U trails by a razor-thin margin of 0.2% in average benchmark score, with the Intel part scoring 1748 versus 1745. This delta is negligible in real-world terms, indicating that the two processors land in the same performance envelope for mixed workloads. The data suggests that for typical mobile tasks—productivity, light content creation, and everyday multitasking—the Ryzen 5 3580U offers essentially equivalent throughput to the i5-8269U, though the latter may hold a slight edge in sustained single-threaded bursts.

The Intel Core i5-5675C edges out the Ryzen 5 3580U by 0.2%, scoring 1742 versus 1745. This is a desktop-class rival from an older generation, yet the gap remains under one percent, highlighting that the Ryzen 5 3580U’s efficiency-focused design does not sacrifice much raw compute capability. In multi-threaded workloads, the Ryzen part’s four cores and eight threads allow it to stay competitive, but the i5-5675C’s higher clock potential in legacy tests might explain the slight lead.

Versus the Intel Core i7-4790T, the Ryzen 5 3580U again sits 0.2% behind, with the i7 scoring 1748. The i7-4790T is a low-power desktop chip with four cores and eight threads, similar to the Ryzen’s configuration. The near-identical average scores suggest that both processors deliver comparable multi-core performance, though architectural differences—Zen+ versus older Haswell—manifest in different single-thread versus multi-thread scaling, which the benchmark breakdowns reveal.

The Intel Core 3 N350 is the closest rival, scoring 1749, a 0.2% lead over the Ryzen 5 3580U. This modern entry-level part achieves parity through higher efficiency per clock, but the Ryzen’s higher boost clock and larger L3 cache (4 MB shared) help it keep pace. In heavily threaded scenarios, the Ryzen 5 3580U’s eight threads match the N350’s configuration, making the performance delta statistically insignificant for most users.

Power and Thermals

The Ryzen 5 3580U is classified in the 15 W TDP segment, which is the standard for thin-and-light mobile laptops. This power envelope implies that the processor is designed for passive cooling in some chassis, or at most a low-profile active cooler with a single heat pipe and small fan. The 12 nm process node from GlobalFoundries, with 4,940 million transistors on a 210 mm² die, contributes to a thermal density that a capable air cooler can manage without aggressive fan curves.

Given the 15 W TDP, the data suggests that sustained multi-core loads, such as Cinebench R23 multi-core, will push the processor toward its thermal limit, but the boost clock of 3.70 GHz is achievable for short bursts. For prolonged rendering or compilation tasks, the chip may settle to a lower sustained clock, but the benchmark scores—6034 in Cinebench R23 multi-core—indicate that thermal throttling is not severe enough to cripple throughput. The lack of an unlocked multiplier means users cannot overclock, so cooling solutions are only required to match stock behavior.

The integrated Radeon Vega 9 GPU shares the same thermal budget, which means that simultaneous CPU and GPU load—common in light gaming or video playback—can strain the cooling solution. However, the 15 W class is well-proven in ultraportables, and the data shows that the Ryzen 5 3580U’s power draw stays within the design limits, making it suitable for laptops with standard thermal modules.

Single-Thread vs Multi-Thread Behavior

The single-thread scores reveal a clear pattern: Cinebench R15 single-core yields 85, R20 single-core yields 357, and R23 single-core yields 851. These numbers are modest for a modern processor, placing the Ryzen 5 3580U below many desktop parts in per-core performance. The 2.10 GHz base clock and 3.70 GHz boost clock are the limiting factors, as Zen+’s IPC is lower than newer architectures. For single-threaded applications—web browsing, office documents, legacy software—the Ryzen 5 3580U will feel responsive but not exceptional, with performance that lags behind higher-clocked rivals.

Multi-thread scores are comparatively stronger: Cinebench R15 multi-core at 608, R20 multi-core at 2534, and R23 multi-core at 6034. The four-core, eight-thread configuration scales well in parallel workloads, as evidenced by the multi-thread to single-thread ratio. For instance, R23 multi-core (6034) is roughly 7.1 times the single-core score (851), which is near the theoretical maximum for eight threads, indicating efficient scheduling and minimal overhead. This behavior suits video encoding, 3D rendering, and software compilation, where the Ryzen 5 3580U can leverage all threads to approach the performance of larger desktop processors.

The split between single- and multi-thread performance suggests that the Ryzen 5 3580U is best suited for mixed workloads that can utilize multiple cores, while single-thread-bound tasks will not see the same benefit. In real-world terms, a user editing a spreadsheet or browsing the web will notice average responsiveness, but exporting a video or running a multi-threaded benchmark will show the processor’s true capability, pulling ahead of single-core-focused chips.

Benchmark Performance

The Cinebench R15 multi-core score of 608 positions the Ryzen 5 3580U in the lower mid-range of mobile processors, but the R20 score of 2534 and R23 score of 6034 show better scaling in newer, more demanding workloads. Compared to its nearest rivals, the Ryzen 5 3580U’s average score of 1745 is 0.2% below the Intel Core i5-8269U (1748), 0.2% below the Intel Core i7-4790T (1748), and 0.2% below the Intel Core 3 N350 (1749), while it is 0.2% above the Intel Core i5-5675C (1742). These deltas are within one percent, meaning the Ryzen 5 3580U is statistically tied with all four rivals in aggregate performance.

Single-core performance tells a different story. The Cinebench R23 single-core score of 851 is low compared to modern desktop chips, but it is consistent with the 15 W mobile class. In contrast, the multi-core scores punch above their weight: the R23 multi-core result of 6034 suggests that the eight threads are effectively utilized, delivering about 7.1 times the single-core throughput. This scaling efficiency is a hallmark of the Zen+ architecture, which excels in parallel tasks despite modest per-core speeds.

When comparing to rivals, the deltaPct values are all under 1%, but the benchmark breakdowns show where the Ryzen 5 3580U wins or loses. For instance, in Cinebench R20 multi-core, the score of 2534 indicates strong threaded performance, likely matching or slightly exceeding the i5-8269U and i7-4790T in multi-threaded tests, while single-thread scores may lag. The Intel Core 3 N350, scoring 1749, achieves its lead through better single-thread efficiency, but the Ryzen 5 3580U’s higher boost clock (3.70 GHz) helps close the gap in bursty workloads.

The percentile rank of 43 indicates that the Ryzen 5 3580U sits in the lower half of all CPUs, which is expected for a 15 W mobile part. However, its average score of 1745 is close to the 1748-1749 scores of its nearest rivals, suggesting that for mobile productivity and light content creation, the processor offers no significant disadvantage. The data shows that the Ryzen 5 3580U is a balanced performer within its power class, with multi-thread capabilities that exceed its single-thread reputation, making it a viable choice for users who prioritize parallel workloads over raw per-core speed.
